In Dungeons and Dragons cosmology (the original one, before Wizards of the Coast took a weed-whacker to it), the 666 Layers of the Abyss are home to demons, the physical incarnations of chaos and evil. One of the few things linking the Layers to one another consistently is the Abyssal Ocean, the domain of some of the oldest and most powerful demon lords and their minions.Some of these minions are more beautiful than others, but that doesn't make them less dangerous.
